Definitions
- the present disclosure relates generally to electronic devices, and particularly, to an electronic device having a remote control capability.
- a typical electronic device with a remote control capability includes a housing, a printed circuit board received in the housing, an infrared communication LED fixed on the printed circuit board.
- the housing defines a through hole. The LED is received in the through hole and extruded from the housing. However, the LED is prone to be detached from the housing by an external force accidentally, thus causing a malfunction of the electronic device.
- FIG. 1 is an isometric view of one embodiment of an electronic device.
- FIG. 2 is a partial, isometric view of the electronic device of FIG. 1 , viewed from another aspect.
- FIG. 3 is a partial, exploded, isometric view of the electronic device of FIG. 2 , the electronic device including a support member.
- FIG. 4 is an enlarged, isometric view of support member of FIG. 3 .
- FIG. 5 is a cross-section of the electronic device in FIG. 2 taken along line V-V.
- FIG. 6 is similar to FIG. 5 , but shows a different state of the electronic device.
- an electronic device 100 includes a housing 10 , a printed circuit board (PCB) 20 , and a light-emitting diode (LED) 30 mounted to the PCB 20 .
- the housing 10 defines a cavity 12 to receive the PCB 20 .
- the housing 10 further defines a through hole 11 on a front side of the housing communicating with the cavity 12 to receive the LED 30 .
- the electronic device 100 further includes a keyboard 13 positioned on a side of the housing 10 .
- the electronic device 100 may be a remote control for household appliances, or a mobile phone, or an electronic key for a car. In the illustrated embodiment, the electronic device 100 is a remote control, and the LED 30 is an infrared communication LED.
- the LED 30 includes an LED chip (not shown), a lens 31 made of resin sealing the LED chip, and two lead terminals 33 extending from a side of the lens 31 .
- the lens 31 is substantially bullet-shaped, and has a curved surface 311 . An end of each lead terminal 33 is bent and welded to the PCB 20 .
- the electronic device 100 further includes a support member 40 fixed on an interior side of the housing 10 to provide support for the lens 31 of the LED 30 .
- the support member 40 which is made of elastic materials, includes a main body 41 , two operation portions 43 , and two fixing portions 431 , and two elastic latch arms 47 .
- the main body 41 is substantially annular, and defines a substantially round positioning hole 45 in a middle portion to receive the lens 31 .
- Two operation portions 43 extend substantially perpendicular to opposite ends of the main body 41 towards the housing 10 .
- Each fixing portion 431 extends substantially perpendicular to an end of one operation portion 43 away from the main body 41 .
- Each elastic latch arm 47 extendslantwise from a sidewall of the positioning hole 45 towards a center of the positioning hole 45 , and face each other.
- Each elastic latch arm 47 includes a free end 471 configured to contact the surface 311 of the lens 31 .
- the free end 471 has the same shape as the surface 311 , and is substantially arcuate in the illustrated embodiment.
- the elastic latch arm 47 is angled close to the through hole 11 , and an angle ⁇ defined by the elastic latch arm 47 and the surface 311 of the lens is about 30° to 60°, in this embodiment the angle is 45°.
- the two fixing portions 431 of the support member 40 are attached to the interior side of the housing 10 by gluing or welding, and the positioning hole 45 is aligned with the through hole 11 .
- the PCB 20 is then received inside the cavity 12 , and the lens 31 of the LED 30 extends through the positioning hole 45 and the through hole 11 , to be exposed from the housing 10 .
- two elastic latch arms 47 firmly clip the lens 31 from opposite sides thereof, to restrict the movement of the lens 31 relative to the housing 10 .
- the electronic device 100 may fall to the ground, or impact with other objects, resulting in vibration or violent shock to the lens 31 particularly along an axis of the through hole 11 . Then, the elastic latch arms 47 clip the lens 31 even more because of the angle ⁇ defined by the elastic latch arm 47 and the surface 311 , to prevent the lens 31 from detaching.
- the support member 40 may be integrally formed on the housing 10 , rendering the fixing portions 431 unnecessary.
- the operation portions 43 may also be omitted.
- the number of the operation portions 43 , the fixing portions 431 , and the elastic latch arms 47 may vary. When there is only one elastic latch arm 47 , the LED 30 is clamped by the elastic latch arm 47 and a sidewall of the through hole 11 .
